Copper phosphorus solder is widely used in the brazing of copper and copper alloys. Brazing performance is strong, in the brazing of copper alloy should be paired with silver brazing agent, phosphor copper silver alloy with good wetting ability, low melting point, can replace some of the high silver solder.

Copper base brazing filler metals belong to high temperature brazing filler metal, widely used in the brazing of low carbon steel and low carbon steel, hard alloy tools brazing, with copper brazing agent can keep high strength of brazed joints.
